"I need to download the macOS 10.15 Hello, Where can I find the download link for Catalina macOS 10.15 version. Catalina 10.15.7 installations says I need to upgrade the computer to 10.15 before I can install it. I am currently running Mojave version 10.14.6"

This is the Link: macOS Catalina 10.15

Important: First, Back Up your Mac:

Create a Time Machine backup of your Mac, so that you can have something to restore your Mac from, should anything go wrong with the reinstall. Take this as a learning experience, knowing to always create a backup of your Mac, prior to making any major changes to it (i.e. update installation)

Sounds like you downloaded the 10.15.7 update from Apple Support Downloads

you can only install these updates if you are already running an earlier version of macOS Catalina.

To upgrade to macOS Catalina you need to download and install the macOSCatalina full installer app

which can only be done through the App Store. The full installer app is called Install macOS Catalina.app

it is 8.26GBs and will install a full working version of macOS Catalina 10.15.7.

Apple removes previous versions of the full installers when the latest / last version is released that is

why there is no 10.15.

For macOS Catalina,

Open Safari and click on this link, 

How to get old versions of macOS – Apple Support

Go to the Download OS section and click on macOS Catalina.

Before upgrading make a full back up of your Mac.

Check that third party apps you use have updates available for the new OS.

https://roaringapps.com

Check that your printers/ scanners etc have updated drivers and software available for the new OS.

Connect your mac to your router via cable rather than rely on WiFi.

Do not use your mac while it is downloading

and do not use any other devices that share the same internet connection.

If the App Store says ‘Open’ then it is detecting a previous download of the install app

go to the Applications folder locate Install macOS Catalina.app.

Move it to the Trash, empty the Trash.

Restart, click on the link again, the App Store should say ‘Get' or 'Download'.

If you want to or are able to install Big Sur, open Safari and click on the link below.

How to upgrade to macOS Big Sur - Apple Support

If you are considering upgrading to Catalina or Big Sur be warned they do not support 32bit apps.

Your Mac is probably running 32bit apps and these will need to be updated to 64bit apps,

some updates may be free, some may be paid. Use this app to discover which apps you have

are 32bit, https://www.stclairsoft.com/Go64/ then contact the developers of the software to see

if they are offering 64bit updates.

You cannot download 10.15 but you can download 10.15.7

Some browsers cannot handle the links on that page. Safari will work. I don't know what others will.

The Age of this computer will Govern what newer version of macOS it will Qualify to install. Use About this Mac from the Apple Icon on Desktop - the required Information will be there.

With the above information in-hand - follow this How to get old versions of macOS and verify what version this computer Qualifies to install. Make sure to use Only Safari to commence the download as Others may not work

Make a Time Machine Backup Before attempting. Notation - Mojave is the Last version to support 32 bit applications / extensions and Drivers. Catalina and Big Sur Only support 64 bit and there is no workaround.

Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation

Use the link I provided in my reply.

This is the Link: macOS Catalina 10.15. Does that not work?

Catalina 10.15.0 is not longer available and not longer offered by Apple. It has been replaced by Catalina 10.15.7 as the last Full Version of this OS.

When you follow the directs supplied by other Contributors - using Safari will open the link and then open a redirect to open the Apple Apps Store where you commence the Download of Catalina - it will be the Full Installer and will be version 10.15.7

This link takes you to download 10.15.7?
